Optimizing Venous Drainage for Minimal Access Right Atrial Procedures.

Abstract

We have created a shaped tube that connects the superior and inferior vena caval orifices to drain the blood from superior vena cava to the inferior vena cava and eventually to the extracorporeal circulation through the femoral vein. We specifically use it in cardiac surgeries in cases of right atriotomy operations requiring femoral vein cannulation, such as tricuspid valvuloplasty or replacement, atrioventricular septal defect repair, and so on. This method would improve the exposure and drainage, simplify operation steps and shorten the operation time.
